Event after finishing textinput?

Hi, is there an event that is caused by finishing an input of a textinput field?

When the user finishes an input, I always have to use a button to continue the operation of the app. It would be easier if the user simply presses the return key of the keyboard (or check symbol on android) and then the app continues work with the input.


We can use a timer to determine if the user entered any final character or define a long pause at the end of the typing, but somehow you need to move the focus from the input field to the keyboard to close.
